Less than a year after it got permission to debut a new availability-based accreditation, MISO is proposing to reformulate how it accredits its resources.

MISO mostly sailed through fall, encountering rough patches only when unseasonably warm weather clashed with generator maintenance season.

Months before MISO debuts a seasonal capacity auction, its IMM said he has uncovered a faulty assumption behind the seasonal capacity requirements.

ISO-NE is narrowing down its options as it moves forward with revamping its process for resource capacity accreditation.

MISO broadcast to stakeholders that it’s ready for a sloped demand curve in its capacity auction.

Stakeholders are seeking a FERC rehearing of MISO’s seasonal auction design, while the RTO wants it to reconsider its minimum capacity obligation.

MISO can establish a seasonal capacity auction and accreditation but cannot require a minimum capacity obligation, FERC ruled in a pair of orders.

MISO said it and the OMS’ annual resource adequacy survey will transition into a seasonal format following its implementation of four-season capacity market.

FERC issued two deficiency letters to MISO over the grid operator’s plans to institute a four-season capacity market and a minimum capacity rule.

MISO's 2022 to-do list will be dominated by getting major transmission built and crafting a seasonal capacity auction.
